Build FAILED.

It seems like the STJ source generator is being run twice. The same also happens with .NET 8.0.3.

Reproduction Steps

Unfortunately I was not able to reproduce the issue outside of https://github.com/database64128/youtube-dl-wpf

Expected behavior

Build succeeds.

Actual behavior

Build fails.

Regression?

Likely a regression of #6792.

Probably also related: dotnet/runtime#68810, reactivemarbles/ObservableEvents#130

None of the workarounds in the above issues work this time.

• .NET 8.0.1: works fine
• .NET 8.0.2: broken
• .NET 8.0.3: broken
